E-Z Clip Series Fitting, 1-1/16-14 Male Insert O-Ring, -12 Hose, Straight

This fitting is made from high-quality materials designed for long-term durability, so it should handle the vibrations and heat from mobile A/C applications, as long as you follow the assembly instructions.

Both, actually. The E-Z Clip fitting is built for refrigeration and A/C systems, and it pairs with a -12 hose in a straight configuration. The male insert O-ring end uses a 1-1/16-14 thread, and the whole system is designed around Aeroquip GH134 Multi-Refrigerant hose. So whether you're working a vehicle A/C job or a refrigeration line, this fitting covers that application.
